Integrated Polymer Sorting

Plastics recyclers need a reliable method of sorting different polymers...

in a mixed material stream to provide a high quality, single polymer output. The Varisort N from S+S Inspection is used by leading plastics recycling companies to produce high purity polymers.

The Varisort N is a complete integrated system and the key to its effectiveness is a combination of robust mechanical design, a full array of Near Infra-Red (NIR) detectors and electronically controlled precision air jet ejection nozzles to identify and remove unwanted fragments with the minimum loss of 'good' polymer.

The feed to the system is a high speed conveyor on which the material is spread evenly with individual bottles and containers singulated before reaching the detector stage where identification technology identifies material within the mixed material stream.

The NIR detector array evaluates multiple wavelengths providing data for industrial PC based analysis software, which determines the position of each piece of unwanted material and triggers the precision ejection nozzles at exactly the right time to blow out the contaminant. Tel: 01489 553740
